electron-withdrawing groups are chlorinated in good to excellent yields (scalable to gram scale) using trichloroisocyanuricacid (TCCA) and catalytic Brilliant Green (BG). Visible-light activation of BG serves to amplify the electrophilic nature of TCCA, providing a mild alternative approach to acid-promoted chlorination of deactivated (hetero)aromatic substrates. The utility of the TCCA/BG system is demonstrated

Bicyclic heteroaryl-substituted imidazole compounds are described, which are useful as H
4
receptor modulators. Such compounds may be used in pharmaceutical compositions and methods for the modulation of histamine H
4
receptor activity and for the treatment of disease states, disorders, and conditions mediated by H
4
receptor activity, such as allergy, asthma, autoimmune diseases, and pruritis.
The invention provides mitogen-activated protein kinase kinase kinase kinase 4 (MAP4K4) inhibitors, and pharmaceutically acceptable salts, hydrides and stereoisomers thereof. The compounds are employed in pharmaceutical compositions, and methods of making and use, including treating a person in need thereof with an effective amount of the compound or composition, and detecting a resultant diminution of tumor cell growth, cancer or metastasis.

The exclusive distribution of 5-HT6 receptors in the brain regions associated with learing and memory makes it an ideal target for cognitive disorders. A novel series of 5-piperazinyl methyl-N-1-aryl sulfonyl indoles were designed and synthesized as 5-HT6R ligands. Most of the synthesized compounds are potent when tested by in vitro radiogland binding assay. The lead compound from the series does not have the CYP liabilities and is active in an animal model of cognition.
